A. Outside Air Kit
A source of air (oxygen) is necessary in order for combustion
to take place. Whatever combustion air is consumed by the
fire must be replaced. Air is replaced via air leakage around
windows and under doors. In homes that have tightly sealed
doors and windows, an outside air source is needed. An
optional Outside Air Kit is available.
Items Needed for Installation (not supplied)
• Needed for option two:
- 4 inch flex aluminum pipe, or if using alternate
material, then it shall be made from durable, non-
combustible, heat resistant material up to 350°F.
- Cut the pipe to the required length for your installation.
• Needed for both options:
- Phillips head screw driver
- 5/32 Allen Wrench
- Silicone sealant
Option One - Installation Instructions
1. Ensure existing access hole in fireplace will not be
covered by the outer can. Existing outside air intake hole
may be under at the rear or side of outer can. Outside
air may also enter down existing chimney chase in some
situations.
2. Level outer can and install appliance. After installing the
appliance in the outer can, seal the fireplace opening
and trim package with insulation to prevent air leakage
into the room.
Option Two - Installation Instructions
3. Ensure existing access hole in fireplace is sufficient to
feed the 4 inch flex.
4. After sliding can into fireplace, feed flex into cut opening
to obtain outside combustion air.
5. Level outer can and install appliance.
NOTE:
Do not use plastic wire ties that come with the kit
as they will melt. You may need to install the flex pipe into
the firebox first depending on installation. Attach flex to
adapter with at least 2 screws.
